overlay: actually disable time_daemon, for good
At least on Focal, time_daemon seems to still be able to run despite
being disabled in init.qcom.usb.rc
. I'm not sure why, but it's
probably related to the fact that this service is also defined in
hw/init.qcom.rc and init.time_daemon.rc.
So, takes another step and overlay the time_daemon executable itself which prevents it from running at all. As this will cause Android init to restart the service every so often, also add a device-hacks snippet to stop that.
